overloading binary operators

New features since Delphi 7 > Operator Overloading > binary operators

The  translation of overloaded binary operators is straightforward. This is shown in the following example:

class operator TMyClass.Add(a, b: TMyClass): TMyClass;

var

  returnrec : TMyrClass;

begin

  returnrec.payload := a.payload + b.payload;

  Result:= returnrec;

end;

becomes in C++ to:

TMyClass operator + (const TMyClass& A, const TMyClass& B)

{

  TMyClass result = {0};

  TMyClass returnrec = {0};

  returnrec.payload = A.payload + B.payload;

  result = returnrec;

  return result;

}

Problematic are the operator IntDivide and LogicalXor because they don't have counterparts in C++. Delphi2Cpp II converts IntDivide to a normal Divide operator /. As long  as there isn't an additional Divide operator this will work. There is no automatic for LogicalXor yet.
